The Organic electrochemical transistors (OECTs) have been received a lot of attentions in bioelectronic devices. [1] Poly(3,4-ethylenedioxythiophene) and poly(styrene sulfonate) (PEDOT:PSS) is the most typical material in OECTs due to its high transconductance and processability. [2],[3] One of the its main drawbacks is that operates in depletion-mode. Here, we have utilized fluorinated benzothiadiazole (BT) groups polymer to demonstrate enhancement-mode OECTs with intrinsic semiconductors by using printing process. We uncover the mechanism that cause the difference in volumetric capacitance due to fluorinated functional group. Then, we investigate how to enhance the ion mobility in the organic semiconductor films. |
